Definitions

  • the invention relates to a method for regulating at least one of the two operating parameters peripheral speed and contact pressure of an inking roller with respect to the forme cylinder in a printing unit of an offset rotary printing press according to the preamble of claim 1 and a printing unit according to the preamble of claim 7.
  • the peripheral speeds of the roller and cylinders should be the same if possible.
  • the potentiometer serving as a control value generator in this printing unit can also be replaced by a pressure load cell which delivers a measured value for the contact pressure of the inking unit roller to the forme cylinder.
  • changes in the diameter of the inking roller can be compensated for, for example, that the roller heats up in operation due to the flexing work between its resilient covering and the printing form, or that the roller is ground a little thinner to level the surface has been.
  • this arrangement cannot compensate for the different peripheral speed between the inking roller and the forme cylinder, which is caused by changes in the application roller diameter, as long as the inking roller and forme cylinder are, as is generally customary, driven by a common drive with a fixed transmission ratio.
  • This inadequate compensation of the peripheral speeds not only causes additional heating and thus an additional enlargement of the roller diameter, but also increased wear on the roller surface, since this runs with increased slip or sliding on the forme cylinder due to the different speeds.
  • an inking unit is known from German utility model 92 15 906.0, in which the inking roller is mounted on two swiveling levers which can be pivoted at one end about an axis fixed to the frame cylinder axis, carry the application roller in the middle between them and at the other end are supported against adjustable stops.
  • Compliant press assemblies press the other ends of the two levers against the adjustable stops.
  • the temperature of the roller surface is measured here and the adjustable stops mentioned are determined with the aid of a computer Adjusted signals in the sense of keeping the strip width constant. The problem of the different peripheral speeds is also not taken into account in the inking unit according to this utility model.
  • European patent application 406 737 suggests that, in order to reduce the slip between the roller and the cylinder that occurs due to the surface contact due to a constant roller diameter, the outer diameter of the elastic peripheral layer of the inking roller is reduced to 99% of the diameter of the same-sized forme cylinder at the same speed of the roller and cylinder. Since all parameters remain constant, an adaptation of the peripheral speed of the application roller to different diameters of the latter is not achieved.
  • the invention solves the problem of creating a control method and an inking unit, by means of which it is possible, for example, when the diameter of the inking roller changes, as a result of heating or wear, the speed of the inking roller deviating from the nominal value and preferably also changes in the width of the application strip between the inking roller having a soft elastic surface and the forme cylinder are to be compensated automatically.
  • this peripheral speed does not always have to be exactly the same as the peripheral speed of the forme cylinder, since the slip which is inevitable due to the non-zero application strip width between the application roller and forme cylinder due to a slight change in the The peripheral speed of the applicator roller can be reduced compared to that of the forme cylinder.
  • the target value for the peripheral speed of the application roller is therefore not necessarily equal to the actual value of the peripheral speed of the forme cylinder. It is easiest to determine empirically.
  • the circumferential speed of the forme cylinder can be entered as a constant in the computer. However, if this is not the case, for example, as a result of fluctuations in the mains voltage, the circumferential speed of the forme cylinder or the speed proportional to this is expediently introduced into the computer as an electrical signal.
  • the invention thus makes it possible to keep the peripheral speed of the application roller, which is generally preselected at the start of the print production, constant during the entire print production, regardless of the surface temperature of the application roller which initially increases with the running time.
  • the peripheral speed of the inking roller can be determined according to a preferred embodiment by detecting the speed of the roller and the diameter thereof.
  • the diameter of the same is expediently determined as a function of the adjustment position of the application roller in relation to the printing cylinder.
  • the peripheral speed of the application roller can also be determined by detecting its speed and temperature, since a fixed relationship arises between the surface temperature of the application roller to be measured and the diameter of the latter.
  • the determined temperature signal can then e.g. are fed to a computer with stored expansion coefficients of the roller.
  • the peripheral speed of the applicator roller can of course also be measured directly, for example using a tachometer. However, this is relatively expensive.
  • the speed of the inking roller does not have to be controlled as a linear function of its diameter.
  • the relationship can also be entered into the computer as a non-linear function.
  • the speed of the inking roller can also be regulated as a function of the Shore hardness of the coating of the inking roller. The harder the covering, the smaller the pressure strip between the roller and the cylinder, and the smaller a possibly advantageous slight reduction in the peripheral speed of the application roller compared to that of the printing cylinder.
  • the regulation of the application strip width in connection with the regulation of the peripheral speed of the application roller can also take place if the roller is mounted so that it can be moved on two slides in the machine frame, as described in detail in German Patent 38 25 517 .
  • the printing unit is equipped not only with a control of the roller circumferential speed, but also with a control of the roller pitch, this has the essential advantage that inking rollers with different Shore hardnesses of the roller surface or with different roller diameters can be used, such as those contaminated by grinding or expired application roller surfaces.
  • the contact pressure or the dependent application strip width and the peripheral speed of the inking roller are of course regulated so that neither an uncontrolled ink transfer nor an undesirable abrasion takes place between the printing form surface and the application roller surface.
  • the invention further develops the printing unit according to the preamble of claim 7 as described in German patent 38 25 517 or utility model 9 215 906, according to the characterizing part of this claim. It is sufficient here that the drive of the inking roller can only be regulated continuously to a small extent, since the expected changes in the diameter of this roller, measured on this, are small.
  • the inking roller can be provided by a separate motor with a controllable speed controlled by the computer.
  • a separate motor with a controllable speed controlled by the computer.
  • Such a training becomes particularly simple since a mechanical control gear is not required.
  • it differs more from the conventional embodiment in which the plate cylinder and the application roller are in drive connection by means of gear drives.
  • a stepless control gear controlled by the computer is arranged in the drive train for the inking roller in front of the latter.
  • Regulating gear of the type in question here can be non-positive or positive; even if non-positive gearboxes are easy to control, a positive-locking gearbox will be preferred because it is subject to less wear.
  • the control gear can be a differential gear e.g. be in the form of a planetary gear.
  • the differential gear can also be an internal gear transmission, in which an internally toothed ring gear meshes with a pinion, the pitch circles of the pinion and ring gear should have a very slight difference. If the point of engagement in such a transmission is rotated at a very low speed, the desired slight change in the peripheral speed of the applicator roller can be easily achieved.
  • the internal gear transmission can in particular be a so-called "harmonic drive transmission".
  • the correct shaft of the differential gear that is, in the case of an internal gear transmission, the shaft which is the point of engagement of the can rotate two gears, is advantageously driven by an auxiliary motor, the speed of which is controlled by the computer.
  • a differential gear instead of a differential gear, another variable speed gear with continuously variable control can be used.
  • the peripheral speed to be regulated has to be regulated very precisely and only in a small range, a differential gear is particularly advantageous.
  • the design of the printing unit according to claim 15 is considered to be particularly advantageous.
  • the swivel levers represent beams that support the applicator roller axis in their center, are supported at one end on the flexible pressing device and at the other end on the bearing in the machine frame. If one measures the bearing force in the machine frame by means of a force measuring arrangement, the measured value is directly proportional to the contact force of the application roller against the printing form.
  • the forme cylinder is advantageously mounted in a stationary manner in the printing unit. The contact forces recorded continuously by the load cell are fed as actual values to a computer provided with setpoints for comparison.
  • Deviating actual values generate a signal in the computer for adjusting the respective pivoting lever, which signal is fed to a DC or AC motor of the adjustment stop via suitable connecting lines.
  • the swivel lever with the inking roller mounted therein is swiveled about or about the swivel lever rotation axis from or to the adjacent forme cylinder.
  • the contact pressure of the inking roller on the plate cylinder can be preset via the central computer of the printing press, or can be influenced by the control station and / or a suitable service device.
  • the load cell can, as I said, be arranged in the frame so that they the bearing pressure of the pivot lever in their frame-fixed storage measures; the load cell can also sit, for example, in the swivel lever and measure the bearing pressure of the shaft of the inking roller.
  • load cells load cells or other suitable force sensors can be used to absorb the bearing force and thus indirectly the contact pressure of the applicator roller against the forme cylinder.
  • the circumferential speeds of the inking roller and the forme cylinder can each be recorded with a tachometer and fed to a computer via connecting lines. Also from the distance of the axis of the inking roller to the unwinding point with the forme cylinder and the speed difference of the forme cylinder to the inking roller, the speed compensation can be formed in the form of a control signal, which as a target value via a connecting line to the actuating device for the auxiliary motor or the control gear of the inking roller is delivered.
  • the setpoint-actual-value speed control of the inking roller can also be carried out on site in a separate control loop.
  • a further advantageous embodiment of the invention consists in that the auxiliary drive motor assigned to the inking roller or the control gear can be assigned a run-up curve, which is defined by the central computer and is parallel or modified with respect to the main drive, in order to adapt the peripheral speed of the inking roller via the corresponding connecting lines.
  • All of these embodiments also allow an application in particular in the case of printing machines with one or more pages, where the contact pressure between the inking roller and the associated forme cylinder is directly dependent on the number of printing forms required for the respective print production.
  • the auxiliary drive motor assigned to the inking roller or the reduction or transmission gear can be used independently of the main drive, so that, for example, a washing process or pre-inking of the inking roller can be carried out.
  • the ink metering swivel doctor blade is advantageously articulated on working cylinders which have constant pressure on the swivel doctor blade or the inking roller. It goes without saying that the ink fountain roller mounted in the ink fountain or the ink fountain as a whole is arranged in a positionally adjustable manner using known means.
  • the section of a printing unit of an offset rotary printing press shown schematically from the side in FIG. 1 has a blanket cylinder 14, against which a form cylinder 2 receiving a printing form is placed.
  • This forme cylinder 2 is associated with a known dampening system (not shown) which transfers dampening solution to the printing form.
  • an impression cylinder 42 - partially shown - is employed on the blanket cylinder 14.
  • the printing material web 41 to be printed is passed between the blanket cylinder 14 and the counterpressure cylinder 42 and printed.
  • An inking roller 1 which has a flexible surface, is also in contact with the forme cylinder 2, which is mounted on the frame.
  • a pre-dosed ink film 43 which has a constant dimension over the entire width of the ink application roller 1 and whose thickness is many times greater than that of the ink film transferred to the forme cylinder 2, is applied to this inking roller 1 with an ink fountain roller (not shown).
  • the pre-metered ink film 43 applied by the ink fountain roller to the inking roller 1 is stripped to a predetermined ink thickness with an immediately downstream squeegee 24 and transferred to the forme cylinder 2 rolling on the inking roller and carrying the printing form.
  • the swivel squeegee 24 is opened, for example, by a known swivel squeegee drive the outer surface of the inking roller 1 is pivoted by an angle.
  • the swivel squeegee is pressed against the outer surface of the inking roller 1 by means of a working cylinder 26 with constant pressure.
  • the inking roller 1 is rotatably mounted in a pivot lever 12.
  • the pivot lever 12 is rotatably mounted about an axis parallel to the inking roller 1 on the frame of the printing press.
  • a load cell 20 is arranged to receive the contact pressure between the forme cylinder 2 and the inking roller 1 and measures the force transmitted from the pivot lever to the frame.
  • a hydraulic working cylinder 23 is articulated, which presses the pivot lever 12 against an adjustment stop 22 so strongly that it always abuts the adjustment stop.
  • the adjustment stop 22 which is fixed in place on the machine frame, has an electrically adjustable spindle 22a, the position of which limits the contact pressure of the inking roller 1 against the forme cylinder.
  • the flattening of the inking roller 1 in the roll-off area with the forme cylinder 2, which determines the width of the application strip and is brought about by the contact pressure, is kept constant by adjusting the pivoting lever 12 when the diameter of the inking roller 1 changes.
  • the contact pressure is measured indirectly via the load cell 20 and fed to the computer 19 via the connecting line 21. This compares the actual values with the target values stored in the computer 19 and accordingly gives a converted control signal via the connecting line 30 to the adjustable adjustment stop 22, which correspondingly adjusts the pivot lever 12 by turning the threaded spindle 22a. In this way, the application strip width 45 is kept constant.
  • control signals to influence the contact pressure can also be given by the central computer 36, the control center 35 and / or a service and test device 37 via the connecting lines 38, 39, 40 to the adjustment stop.
  • Fig. 2 shows the data flow and the power flow for speed control of the inking roller 1 according to the illustration in Fig. 1.
  • the form cylinder 2 driven by the blanket cylinder 14 and the inking roller 1 driven via a reduction or transmission gear 5 or intermediate gear pair 4 have coaxially arranged on its axis of rotation, each have a tachometer generator 17, 18 for recording their actual speeds, which are fed to a computer via connecting lines 27, 28.
  • the load cell 20 arranged at the pivot point of the pivot lever 12 detects a resulting actual contact pressure component between the forme cylinder 2 and the inking roller 1. This value is fed to the computer 19 via a connecting line 21.
  • the auxiliary motor 8 is also assigned a tachometer generator 16, the measured values of which are fed to the computer 19 via the connecting line 21.
  • the computer 19 calculates the new adjustment position of the inking roller 1 from the adjustment path of the calibrated spindle 22a of the adjustment stop 22 and the lever ratios between the pivot point of the lever 12 to the axis of rotation of the inking roller 1 or to the distance from the spindle axis of the spindle 22a.
  • the distance between the axis of rotation of the new adjustment position of the inking roller 1 and the unwinding point with the forme cylinder 2 gives the new effective radius or extent of the inking roller 1.
  • a separate control circuit 44 is assigned to the auxiliary drive motor 8 in order to achieve better control dynamics of the inking roller 1 and to maintain the desired peripheral speed.
  • the speed of the auxiliary motor 8 can also be set via the central computer 36 and / or the control station 35 or a third-party device as a service device 37 via the connecting line 38, 39, 40 by means of a desired operator value.
  • Fig. 3 shows schematically the mechanical drive of the inking roller 1.
  • a gear 3 is rotatably attached, which from the main drive of the printing machine via the gear 13 of the blanket cylinder 14th is driven at the same speed.
  • the gear 3 meshes with the gear 5.1 on the drive side of an adjustable differential gear 5.
  • the gear 5.2 of the differential gear 5 rotating on the output side with a slightly adjustable speed meshes with a gear of the idler gear pair 4.

  • the location of the sensor 20 and / or the gear pair 4 may also be different.
  • the drive gear 5.2 rotates accelerated or decelerated relative to the drive gear 5.1.
  • a "harmonic drive gearbox” consisting of a “wave generator” with an elliptical steel disc with a central hub and a mounted, elliptically deformable ball bearing, a “Flexspline”, formed from a cylindrical, deformable steel sleeve with external teeth and the " Circular spline ", a cylindrical ring with internal teeth.
  • the elliptical wave generator as a part driven by the adjusting shaft 6, deforms the flexpline via the ball bearing, which is in engagement with the internally toothed, fixed circular spline in the opposite areas of the large ellipse axis.
  • the speed of the wave generator with the controllable auxiliary motor 8 is increased or preferably reduced via the adjusting shaft 6.
  • the large ellipse axis and thus the meshing area are shifted. Since the Flexspline has two teeth less than the Circular Spline, after half a revolution of the wave generator there is a relative movement between the Flexspline and Circular Spline by the size of one tooth, and after a full revolution by the size of two teeth.
  • FIGS. 4 to 6 shows a section of a printing unit, corresponding to the description according to FIGS. 1 to 3, in which the inking roller 1 can also be turned on and off to maintain a predetermined contact pressure on the forme cylinder 2, but with a direct, electrically controllable rotary drive for the inking roller 1.
